MANUFACTURE OF TOBACCO-LIKE PAPER.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed December 19.1903'. Serial No. 185,890.

lie it known that l, llmnuxx Arm, :1 subject of the (iraud Duke oi Baden, residing at lionstanz, Baden, Empire of Germany, have invented a certain new and useful Improved .\lanul'acture ol 'lobacco-Likc laper, of which be following is a specification.

This invention relates to a process for manul'aeturing a paper which when burned gives very nearly the same aroma and taste as a tobacco leaf or wrapper. For this purpose is specially prepared by a special pi'ocess forming the object of this invention.

The process consists in raw paper being impregnated with a tobacco decoction, which is allowed to ferment in the paper. it fresh nutcrmented tobacco docoction is used, the paper inqiregnated with it must be kept in a wet state for a time in order that the fermenting process may take place. It, however, a decoction that has already stated to formont is used. the timeduring which the paper is required to stand willbc (:(HlSlilOltlhlY reduced. The raw paper can be either thin paperor tissue made from ordinary paper-paste, or it may be a paper prepared in the wellknown manner from parts of the tobaccoplant. such s the Veins and Waste.

In order to make tlu. process clearly understood. an example will be described explaining the different stages of the process. The raw paper utilized in this example is supposed to be prepared from parts ot the tobacco-plant. In order to produce the paper, tobacco leaf. Veins, or libcrs are cleaned and broken up and then placed in a water solution of hydrate of lime mixed with ten per cent. ll \'(ll'0(..lllOI'iC acid. The material is left in the solution for about four to eight days until it becomes perlertly sol't and with line libers The material then is washed, ground, and made into paper. ten to forty percent. or pulp rags or collulosc) being added. The paper should weigh lrom sixteen to twenty grains per square meter. The paper as received from the paper-making machine is thoroughly wctted with tobacco decoction by mean of a suitable device. the composition of tho 'iccoction being described below. The tobacco decoction isobtained by boiling ground tobaccoin water, so as to ex tract from it all aroma and its principal ingredients. The whole is then well pressed out. in order to obtain a good aroma and taste when burning, to]iacco-powdcr of a good kind and spices such as are generally used I with the (leeoction obtained in the above man- I l l r l l l ner is arranged in several layers or rolled up and stored in an air-tight t'ermcntingchamber kept at a temperature of about 37 ccntigradc. During the time it. is left to stand the dccoction contained in the paper begins to ferment in the same way as tobacco. .-\ccording to the tour perature at which the paper is kept the t'ermentation takes place earlier or later, said fermentation manifesting itself by the increase of temperature and swelling of the paper arranged in layers and by the sweating oi the inner walls of the fermenting-chamber. Thus, for instance, after the paper has been lift for a few weeks the temperature rises from 1.5" or ZOlccntigradc to 24: centigrade in the case of a decootion obtained by boiling one here dred and fifty grams of fairly finely pulverizcd tobacco for two hours in six huiulrcd cubic centimeters of water having been used, one hundred and iit'ty grams of Very line tobacco-powder having been added to the warm decoction. if desired, the tobacco decoction may be in a state of fermentation or be t'ermcnting at the time the paper is impregnated, in whicheventtho time d uring which the paper is required to stand will be considerably reduced. The paper, which has become rough owing to the treatment with tobacco decoction. is smoothed and only requires to be cut to the size required in order to be ready for use.

()wing to the action of the fermentation of the tobacco decoction on the paper which is impregnated with it.the paper when burning is verysimilar to tobacco as regards the, taste and aroma.

The paper obtained in the manner described can be used as. cigarette-paper and also to replace the outer layer of tobacco on the cigars or for packing tobacco, cigarettes, or cigars.

\Vhat I claim as myinvcntion, and desire to secure by Letters Patent, is e 1. In the mamil'acture ot' a tobacco-like paper, making a thin paper from paper-pulp or from linely-grouml parts of the tobaccoplant, impregnating the paper with a tobacco decoction, subjecting the impregnated paper to a fermenting process, at afermenting temperature, and finally smoothing the paper, substantially as described.

2. in the manufacture of a tobacco-like paper, making a thin paper from paper-pulp or from finely groundparts 9f the tobaccoplant, impregnating the menting tobacco decoetiomand finally smooth I ing the paper, substantially as described.

A tobacc -like paper prepared by treatpaper with a folwith a tobacco (lecoction, and then subjecting the impregnated paper to a fermenting process, substantially as described.

In testimony whereof lhave signed my name ing paper to this specification in the presence of two sub- 5 scribing witnesses.
